Oct 4, 2017. Three pioneers of this field were awarded Nobel Prize in Chemistry 2017

Three pioneers of this field were awarded Nobel Prize in Chemistry 2017

  • Jacques Dubochet (University of Lausanne, Switzerland) is a pioneer of ice-embedding method of EM specimen (as known as cryo-EM), Most of 3DEM structures in EMDB and PDB are obtained using his method.
  • Joachim Frank (Columbia University, New York, USA) is a pioneer of single particle reconstruction, which is the most used reconstruction method for 3DEM structures in EMDB and EM entries in PDB. And also, he is a develper of Spider, which is one of the most famous software in this field, and is used for some EM Navigor data (e.g. map projection/slice images).
  • Richard Henderson (MRC Laboratory of Molecular Biology, Cambridge, UK) was determined the first biomolecule structure by EM. The first EM entry in PDB, PDB-1brd is determinedby him.

Jul 12, 2017. Major update of PDB

Major update of PDB

  • wwPDB released updated PDB data conforming to the new PDBx/mmCIF dictionary. This is a major update changing the version number from 4 to 5, and with Remediation, in which all the entries are updated. See below links for details.
  • In this update, many items about electron microscopy experimental information are reorganized (e.g. em_software). Now, EM Navigator and Yorodumi are based on the updated data.

Yorodumi

Thousand views of thousand structures

  • Yorodumi is a browser for structure data from EMDB, PDB, SASBDB, etc.
  • All the functionalities will be ported from the levgacy version.
  • This page is also the successor to EM Navigator detail page, and also detail information page/front-end page for Omokage search.
